I have a weather station software, connected to the ez200F that waits to get DSR = 1, but it never receive this signal and then send a 'sConnection timeout's Does ez200F needs to have a specific configuration to receive this signal ? Thanks Christopher ps : below a part of the code if (!GetCommState (ws, &dcb)) { printf (" Unable to GetCommState"); exit (0); } dcb.DCBlength = sizeof (DCB); dcb.BaudRate = BAUDRATE; dcb.fBinary = FALSE; dcb.fParity = FALSE; dcb.fOutxCtsFlow = FALSE; dcb.fOutxDsrFlow = FALSE; dcb.fDtrControl = DTR_CONTROL_DISABLE; dcb.fDsrSensitivity = FALSE; dcb.fTXContinueOnXoff = TRUE; dcb.fOutX = 0; dcb.fInX = 0; dcb.fErrorChar = FALSE; dcb.fNull = FALSE; dcb.fRtsControl = RTS_CONTROL_DISABLE; dcb.fAbortOnError = FALSE; dcb.XonLim = 0; dcb.XoffLim = 0; dcb.ByteSize = 8; dcb.Parity = NOPARITY; dcb.StopBits = ONESTOPBIT; dcb.fNull = false; dcb.XonChar = NULL; dcb.XoffChar = NULL; dcb.ErrorChar = NULL; dcb.EofChar = NULL; dcb.EvtChar = NULL; if (!SetCommState (ws, &dcb)) { printf (" Unable to SetCommState"); exit (0); } commtimeouts.ReadIntervalTimeout = 0; commtimeouts.ReadTotalTimeoutMultiplier = 0; commtimeouts.ReadTotalTimeoutConstant = 0; commtimeouts.WriteTotalTimeoutConstant = 0; commtimeouts.WriteTotalTimeoutMultiplier = 0; if (!SetCommTimeouts (ws, &commtimeouts)) { printf (" Unable to SetCommTimeouts"); exit (0); } for (i = 0; i < 2000; i++) { buffer[i] = 'sU's; } write_device(ws, buffer, 2000); set_DTR(ws,0); set_RTS(ws,0); i = 0; do { sleep_short(10); i++; } while (i < INIT_WAIT && !get_DSR(ws)); if (i == INIT_WAIT) { print_log(2,"Connection timeout 1"); printf ("Connection timeout "); exit(0); }
